A route is reported for the synthesis of two electron-accepting phthalocyanines featuring linkers with different lengths as sensitizers for p-type dye-sensitized solar cells (DSSCs). Importantly, our devices based on novel nanorod-like CuO photocathodes showed high efficiencies of up to 0.191 %: the highest value reported to date for CuO-based DSSCs.
Keywords: CuO electrodes; CuO nanorods; dye-sensitized solar cells; electrochemical impedance spectroscopy; zinc phthalocyanines.
